Service windows

Some technical procedures may require some service downtime for some set of services. We are determined to keep this time as short as possible and try to schedule any downtime in a way that it would cause as little inconvenience as possible for our customers. The announced service windows are the maximum time frames during which there might be some glitches in services.
